I am having a problem connecting and sending Bluetooth low energy data from a custom built app I created in android studio to a BLE dongle. The app I created has 4 virtual push buttons and every time I press one these buttons its send a 4bit number letting the Bluetooth dongle( peripheral) know. The problem is that when I use "hcidump" in Linux I cant read anything. which I figured is how I can view this data.
One of the problems I believe I am having is that I need to advertise some command that lets the app know what information I want. If this is the case I'm unsure what to send, to notify the app that I want to read the states of the virtual pushbuttons.
I am able to bring up the ble dongle in Linux and the app is able to discovery the ble dongle as well they will connect for a short period then disconnect cause as I said the app is waiting for some kind of characteristic/service or so is what I believe?
